.TH GNUNET.CONF "5" "12 Aug 2013" "GNUnet"
.SH NAME
gnunet.conf \- GNUnet configuration file
.SH SYNOPSIS
~/.config/gnunet.conf
.SH DESCRIPTION
.PP

A GNUnet setup typically consists of a a set of service processes run by a user "gnunet" and a set of user-interface processes run by a standard account.  The default location for the configuration file for the services is "~gnunet/.config/gnunet.conf"; however, as normal users also may need read-access to this configuration, you might want to instead put the service process configuration in "/etc/gnunet.conf".  gnunet\-setup (part of the GTK package) can be used to edit this configuration.  The parts of GNUnet that is ran as a normal user may have config options too and they read from "$HOME/.config/gnunet.conf". The latter config file can skip any options for the services.

.TP
The basic structure of the configuration file is the following.  The file is split into sections.  Every section begins with "[SECTIONNAME]" and contains a number of options of the form "OPTION=VALUE".  Empty lines and lines beginning with a "#" are treated as comments.  Almost all options are optional and the tools resort to reasonable defaults if they are not present.
.PP
Default values for all of the options can be found in the files in the "$GNUNET_PREFIX/share/gnunet/config.d/" directory. A typical setup will work out of the box with those. See the examples section below for some common setups on top of that.

.SH General OPTIONS
.PP
Many options will be common between sections. They can be repeated under each section with different values.  The "[PATHS]" section is special. Here, it is possible to specify values for variables like "GNUNET_HOME".  Then, in all filenames that begin with "$GNUNET_HOME" the "$GNUNET_HOME" will be replaced with the respective value at runtime.  The main use of this is to redefine "$GNUNET_HOME", which by default points to "$HOME/.config/".  By setting this variable, you can change the location where GNUnet stores its internal data.
.PP

The following options are generic and shared by all services:

.IP HOSTNAME
    The hostname specifies the machine on which the service is running.  This is usually "localhost".
.IP BINARY
    The filename that implements the service. For example "gnunet-service-ats".
.IP FORCESTART
    Start the service always when the peer starts.  Set to YES for services that should always be launched, even if no other service explicitly needs them.
.IP AUTOSTART
    Set to YES to automatically start the service when it is requested by another service. YES for most GNUnet services.
.IP NOARMBIND
    Set to YES to never have ARM bind to the respective socket. This option is mostly for debugging in situations where ARM cannot pass the pre-bound socket to the child due to interference from PREFIX-commands.  This option is only effective in combination with FORCESTART being YES.  NO by default.
.IP PREFIX
    PREFIX the given command (with its arguments) to the actual BINARY to be executed. Useful to run certain services under special supervisors (like strace or valgrind).  Typically used in combination with FORCESTART and NOARMBIND. Empty by default.
.IP ACCEPT_FROM
    A semi-column separated list of IPv4 addresses that are allowed to use the service; usually 127.0.0.1.
.IP ACCEPT_FROM6
    A semi-column separated list of IPv6 addresses that are allowed to use the service; usually ::1.
.IP UNIXPATH
    Path to use for the UNIX domain socket for inter process communication with the service on POSIX systems.
.IP UNIX_MATCH_UID
    If UNIX domain sockets are used, set this to YES if only users with the same UID are allowed to access the service.
.IP UNIX_MATCH_GID
    If UNIX domain sockets are used, set this to YES if only users with the same GID are allowed to access the service.
.IP USER_SERVICE
    Set to YES if this service should be run per-user, NO if this is a system service.  End-users should never have to change the defaults GNUnet provides for this option.

.SH EXAMPLES

This example is a simple way to get started, using a server that has a known list of peers to get you started. Most users will be behind a firewal on IPv4, as such NAT is enabled.  Please rememeber to change your IP address to the actual external address for your usage.
